ATTACHMENT FOR LADDERS.

Specification of Letters Patent. ippncafion m June 15,1905. semi No.265,376.

Patented Jan. 2, 1906.

To aZZ whom it may concern;

Be it known that I, J AMES K. HEsTER, a citizen of the United States,residing at Rhinecliff, in the county of Dutchess and State of New York,have invented certain new and useful Improvements in Attachments forLadders; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in ladders.

The object of the invention is to provide an attachment of thischaracter adapted to be applied to the lower end of one of the side barsof a ladder to increase the length of the same, thereby permitting theladder to stand level on uneven surfaces.

A further object is to provide means whereby very slight adjustments maybe given to the lengthening attachment.

With the above and other objects in view the invention consists ofcertain novel features of construction, combination, and arrangement ofparts, as will be hereinafter described and claime In the accompanyingdrawings, Figure 1 is a perspective view of a portion of a ladder,showing the application of the attachment thereto.

ig. 2 is a vertical sectional view of the same.

Fig. 3 is a horizontal sectional view through the leg of the ladderhaving the attachment applied thereto.

Referring more particularly to the drawings, 1 denotes the ladder, whichmay be of any desired construction having the usual side bars 2,connected by rungs 3. In the lower end of one of the side barsof theladder is formed a series of horizontal transverselydisposed apertures4, said-apertures being arranged in zigzag order, whereby a considerablygreater number of apertures may be formed without danger of the woodbetween the same breaking or splitting out. Slidably mounted upon saidapertured leg of the ladder is a sleeve 6, said sleeve being preferablyof a length corresponding to the distance between the lower rungs of theladder and the lower end of the side bar. The

sleeve 6 is here shown as being rectangular in cross-section andprovlded with a. rectangular passage to correspond with the rectangularshape of the side bar. These parts, however, may be of any desired shapein crosssection. In each side of the sleeve 6, near the upper end of thesame, is formed a pair of oppositely-disposed apertures 7, saidapertures in each pair being offset and arranged one slightly above theother, so that when the sleeve is adjusted on the end of the side barone or the other of the apertures in said bars will be brought oppositeto and into alinement with one of the apertures 4 in the side bar. Afterthe sleeve has been thus adjusted to the desired extent a pin or bolt 8is inserted through the alined apertures in the sleeve and side bar,thereby securely holding the sleeve in its adjusted position.

By means of an attachment of the character described a ladder may beused on uneven surfaces or sidehills without danger of the same tippingor falling over.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a. more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the princicipleor sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The herein-described attachment for ladders, consisting of a plain,hollow, rectangu- HGSSGS.
